Backpack-01.JPG
A thin teenage girl carries a very large backpack. Carrying a too-heavy backpack can cause chronic shoulder, neck and back pain, but many school-age children carry huge backpacks everyday. If the backpacks exceed the child's body weight by 15%, or if they carry it on one shoulder, it may be harmful.
